High CVSS 7.7
CVE-2026-55729
Exposure of Sensitive Information (CWE-200) in LWEB802 browser `localStorage` in Loytec LWEB-802 before 5.0.8 on all platforms allows an unauthenticated remote attacker to leak stored management credentials via a crafted link.
What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content. It also depends on circumstances the attacker does not control.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- The application reveals information an unauthorised user should not see.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
